The easy approach is to use a program like GPSBabel to rewrite the file by doing a GPX to GDB conversion. The typical failure is from a lack of proper GPX Header in the file. Many of the [great] free user programs out there don't write proper headers because they don't expect anyone to actually "share" their data with anything that cares - many GPS's don't care about "header" data - like Google Earth.

If GPSBabel finds an error it will show you where the error is. At that point if you are comfortable at editing GPX data, then open the file in your XML editor and fix the bad syntax or data. Here is where you will have to understand what valid data looks like in a GPX file as well as the different GPX XSLT's that Garmin has used over the years for their Extensions. In the past some of the early Garmin GPX syntax's were not read by BaseCamp: i.e, cause an error. I don't know if they fixed all of that.

I think some of the problem with existing routes is waypoint related...I've got dozens of routes that go back several versions of City Navigator..I always reload them in the latest CN and regenerate the route before loading on my Montana, but I've had several routes that give me the " maps don't match the route" message and a subsequent refusal to recalc. I'm too lazy to look at the GPX file and see if there is any version related info hooked to the waypoints that won't update unless you regenerate the waypoints in the same version of CN (on the GPS) that you have in Mapsoure or Base camp...

There is no map specific data associated with Waypoints. That is why Waypoints (assuming the data is valid) will always transfer from GPS to GPS. Routing data is the issue when it comes to Map Versions. That Routing Data is provided by the Map and if it does not correlate with the data that is in the use to define the Route you are sending the GPS will have "issues". Most likely the issue is that the Waypoint is no longer within the road data that it was originally or it is on an Intersection - which can cause routing issues on the Montana.

There are obviously still issues with routing. Any other GPS would simply recalculate the route - which would most likely change the original path. In order to meet customer requests that Routes created on the same map sets NOT be recalculated the Montana code was written to not EDIT (recalculate) these routes. But, when there is a routing condition that would require any path change the code runs into it's on self imposed constraints. Therefore the error. By the way, that's all subjective speculation on my part.

My Montana is hooked into switched power on my bike. I noticed the other day that it only had 1/2 battery charged even though it showed the lightning bolt. When I turn key off it always asks me if I want to run it off battery or let it shut down. It seems to be acting "normal".

I leave the Montana in the cradle and key in ignition in my garage. Today it was completely dead. Of course, when turning the key it fired up like normal. Does this use up battery even when shut down? It's not a huge problem, just a minor annoyance. I used the same switched source on my zumo with none of these shenanigans. Is this another Montana quirk?

I guess that's the confusing part to me. There is no power going to it while the key is off. It seems odd that the battery would drain while sitting in the cradle with no power going to it. I don't have the problem if I take it off.

Sounds like maybe your Lithium battery is not preforming as it should. Does the battery charge completely if you charge it via USB? If it does leave it out of the Mount in a Powered Off condition and see if it holds a charge overnight - it should most definitely.

The unit does not use much power when truly Powered Off. If the Montana is in the Mount and the Mount is hot all of the time the unit will continually charge the battery (very small amount of current) even when the Montana is Powered Off.

Just saw your post above...I'd say you have a connectivity issue with your switched power to the Mount. I would recommend removing your Montana from the Mount when you are not using it.

Sounds like you have a complete circuit somewhere, even with the key off.

It's the Montana or should I say the mount. Mine does the same and yes, it's a PITA. My other 4 Garmin units never did this. You could leave them in for months with no problem. With the Montana, after a day or two it's drained I'm guessing there is something in the mount that is drawing power.

It would be worth trying an experiment - my mount is connected via SAE plug - if I leave the Montana in its mount with the power connector unplugged, I wonder if it will die the same way?

This would tell us if it's the mount, or the connection to the bike's electrical system which is the problem.

I don't leave my Montana in the garage, though, normally.

That would do it I had thought of disconnecting my mount but it's hardwired so a little too much effort. And, if I go take the time to do that then I just may hardwire it hot. The 476c (or was it the zumo) had a power option to stay on or power down when loss of power was detected. I've asked Garmin to give us this option on the Montanan too.
